PIPE-ORGAN.

Specification of Letters Patent.

Patented Oct. 5', 1920.

Application filed December 15, 1916. Serial No. 137,091.

To all '2U/7mm. t may concern.'

Be it known that I EARL G. SCHWARZ, a citizen of the United tates of America, and a resident of Fighland, in the county of Madison and State of Illinois, have invented certain new and useful Improvements in Pipe-Organs, of which the following is a specification.

One of the objects of this invention is to provide improved means whereby the pedals pertaining to the bass pipes of pipe organs can be done away with, and the same can be operated and controlled by the keys of a piano.

Another object is in providing an improved solo attachment which is comprised of an electrical wiring system coperable with the bass pipe keys of a pipe organ, in which the lowest key operated upon will automatically cut out and prevent any higher note or notes from being sounded at the same time.

Other and further objects will appear in the specification, and be specifically pointed out in the appended claims, reference being had to the accompanying drawings exemplifying the invention, and in which,

Figure 1 is a fragmentary plan view of a portion of a pipeorgan showing the organ and pedal pipes and their respective pipe chests.

Fig. 2 is an enlarged fragmentary section taken on the line H II of Fig. 1, showing one of the two-stop actions.

Fig. 3 is an enlarged fragmentary section taken on the line III-IH of Fig. 1.

Fig. 4 is an enlarged fragmentary section ofa portion of a piano showing a portion of a mechanical player attachment applied thereto.

Fig. 5 is an enlarged fragmentary section taken on the line V-V of Fig. 1.

Fig. 6 is an enlarged fragmentary hori- Zontal section taken approximately on the line VI-VI of Fig. 5.

Fig. 7 is an enlarged fragmentary hori- Zontal section taken on the line VII-VII of Fig. 4.

Fig. 8 is an enlarged 'section taken on the line VIII-VIII of Fig. 7 showing the form of electrical contacts used in connection with the pedal keys.

Fig. 9 is a fragmentary diagrammatic view showing the improved system of electrical wiring relative to the contacts of the piano keys..

Referring to the drawings, and more especially to jig. 4, 1 designates a portion of a plano having the usual eighty-eight piano keys 2, and operably related to said keys are the vertically arranged abstracts 3 that are adapted to operate the striking hammers 4 when the piano alone is being played. Located adjacent the hammers 4 is the hammer rest rail 5. Operably related to the abstracts 3 is a player operating device 6 that is controlled by the music roll 7.

Carried by each of the members 3 is a lug 8, each of said lugs being for the purpose of engaging sets of contact members such as 9 and 10, there being a set of said contact members 9 and 10 to each piano key 2. Leading from said contact members 9 and 10 respectively are contact wires 12 and 13, said wires leading to the pipe organ, which might be located vat any distance away from the piano.

Referring now to the pipe organ, :arranged in 'said organ is a primary pressure chest 14, and located in said chest is a plurality of electromagnets 15, each of said magnets having a hollow core 16, there being a magnet 15 for each of the piano keys 2, each set of said circuit wires 12 and 13 leading to one of the magnets.

Operably related to the hollow core 16 of each of said magnets 15 is an armature 17, each of said armatures 17 being adapted to control an'exhaust port 18. Communicating with the lower end of each of the hollow cores 16 of each magnet 14, and leading therefrom to a valve-operating bellows 19 is a passageway 20, said bellows 19 being located in a secondary pressure chest 21.

Depending from each bellows 19 is a valve stem 22, and carried by said stems 22 are a pair of valves 23 and 24, each of said vvalves 23 controlling a port 25, whereas each valve 24 is adapted to cont-rol a port 26, each set of said ports 25 and 26 communicating with their respective passageways 27.

Communicating with each passageway 27 and located in said chest 21 is a valve operating bellows 28, each of said bellows 28 being adapted to operate a set of valves 29 and 30, said valves controlling ports 31 and respectively. Communicating with each set of said ports 31 and 32 is a passageway 33. Leading from each of the passageways 33 are a series of tubes 34, each of said tubes 34 communicating with. a passageway 35. in comtermination with a valve operating; bel

lows 36, there being a series of said bellows located in each of the stop chests 37, each of said stop chests 37 having eighty-eight pipes 38 mounted thereon, each of said pipes being Vcont-rolled by a set of valves 39 and 40,`each o't' said sets of valvesbeing controlled by one of the valve operating bellows V36, each set of said valves 39 and 40 controlling a passageway 4l which is adapted to form communication between each pipe 38 and its ref spective stop Ychest 37. From the disclosure shown 1n the drawings, and in the aforesaid description, in

which there are four transversely arranged stop chests 37, each chest'being adapted to contain eighty-eight pipes, it is to bescen that each of the piano lreys'2 is operably related to tour iaes or one aise to each of the four chests shown, although any num-l ber of chest-s can be used in each case, as a single piano key will be capable of operating'A any desired number of pipes.

Mounted above vthe chests 37 at each enc v thereof is a primary valve chest 42, and a secondary valve chest'43. Located. in eachVV of the chests 42 1s a series of hollow coredl magnets 44, each core of each of said magnets leading to a vent 45. f As shown in Fig.,

2, each of the chests 37 is divided by a partition 46, thereby providing a pair of compartments A and B in each chest 37, in

which one set of chests 42 and 43 is related to all of the compartments A, whereas the other set of chests 42 and 43, arranged Vin v.the opposite-side, is related to all of thecom- 44, and there being a magnet ter each ot the compartments ,A and a magnet for each of the compartments B of each chest 37.

Leadmo to each set of valves 49 and 50 is a passageway 51, each of said passageways communicating with a valve'operating bellows 52, there being four of each of said'Y bellows 52located in cachot said valve chests 43. Each of said bellows 52 is adapted to control an inlet Vvalve 53, each'of said valves controlling a port 54, said ports being located on the top side adyacent the ends of each of the stop chests 37 and adapted tof control theiadmissionof air to thinr compartments A and B.

Leadingrfrom each of the magnets 44 are circuit wires 55 and 56, said wires 56 being in communication with one of the supply wires 57, whereas said wires 55 lead to the terminals 58. Operably related to each ot the terminals 58 are control terminals 59,V

andi-leading from each ot said terminals'59 isa wire 66, in communication with the supply wire 61. l. Y I Referring to Fig. 3 Vof the drawings, which discloses the control mechanism to each of the bass pipes 62, which are mount- Ved on the bass Ypipechest 63, said pipes being in communication with a'hori'zontally arranged passageway 64 which is in communication with the chest 63 through respective portsr65.V Gppositely disposed from each of said ports 65 is aport 66, said ports 65 and 66 being controlled by valves 67 and 68 rcspectively,y each 'set ot' said valves being operated byra bellows69, there being series of said bellows located in Ythe chest 63. Communicating with each bellows 69 is a passageway 70, one end of each of said passageways being in communication with a hollow core 7l er' a magnet 72, there being a magnet '72 for each pipe 62, said magnets being located in a chest 75. Coperable with each core 7l is an armature 73, each arma-y tureY controlling a hollow core 7l and a respective passageway 74, there beinga passageway 74 for each magnet 72; v

@perable with each vlug 8 of each abstrac 3 is an electrical contact member normallyin engagementwvith said member 76 is a contact member 77. Normally held away from said contact member 76 is a contact' member 78, each set of said Contact members 76, 77 and 78 being coperable with cachot the pipes 62 and their respective operating mechanisms. Leading Vfrm/n each Contact member 78 toa supply wire 7 9 is a wire'86, and leading from -eachcontact niember 76 ot each set of bass pipe contact menibers to an adjacent contact member 77 wire 8l. y i

From an inspection et' Fig. 9' it will be seen that the contact members 77 are non mally in engagement withV their respective adjacent contact members 76j, Veach set ot Y Contact vmembers 76 and 7 7 being in communication through their vrespective'wires 8l.

ln the operation of Ythis improved device relative to the sounding of the pipes 38, as-v suming that Lcurrent is supplied to the wires K l2 and 13 which are coperable with each key 2, when a number of the keys Vare opcrateri, the abstracts 3 upon being elevated will cause the lugs 8 of said abstracts 3-to VV'move the "centactsf) against respective contacts l0, thereby closing the circuits of the sets of wires l2 Vand 13 and the armaturel7 of veach magnet l5 will be drawn upwardly against fitsv respective hollow core l16, thereby allowing th'eair which Ais in the bellows 19 toA vent through its respective passageway 20 and vent 18, and since air pressure is maintained in the chest 2l, saidvbel- Ylows 19 are collapsed and the valves 23'will be elevated from their ports 25, and at the 76, andV ilo , Yleaner/,e

yair will be admitted into Vsaid passageway and into the bellows 28 that are in a recep-` tive condition, thereby expanding said bellows and engaging the valves 29 against their respective ports 3l, and at the sameV time diseng'aging the valves 30 from their respective ports T his will allow the air from .the passageways 33 to vent through the ports and instantly the air which is in the passageways 35 of the stop chests 37 will vent, the air in said stop chests collapsing the bellows 36, thereby moving fthe valves 39 andr e0 so that air will be admitted the chests 37 to the passageways Lll i irom and to their'respective pipes 38, thereby sounding said pipes. During'the aforesaidV operation, if it is desired to play the organ without sounding the piano, the hammer rest rail 5 is moved to the position shown in dotted lines in which instance the piano hammers 'Ll will be held against the piano strings, not shown.

If it is desired to play the organ mechanically the player mechanism 6 is put into operation, in which instance the lifting members 83 of said mechanism 6 will cause the abstracts to be elevated instead of the piano keys 2.

It is obvious that if the piano is to be played alone, either mechanically or manually, the electric circuit relative to the contact members 9 and 10 can be denergized.

When it is desired to opera-te the treble side only of any one of the chests 37, the right hand control terminal 59 is engaged against its respective terminal 58, vthereby closing the circuit relative to the wires and 56, in which case the armature of the elected hollow cored right hand situated magnet will be drawn against the hollow core thereof from against the passageway 45, thereby allowing the air to be exhausted through the passageway 47 from the bellows d8, in which instance the valves 49 and 50 will be displaced, thereby allowing the air .from the passageway 5l to be exhausted from the bellows 52 through the port 841, and since air pressure is carried in the chest 43, said bellows 52 will be collapsed, thereby elevating the valve 53 from the port 54e and allowing air pressure to be admitted from said chest e3 to the B compartment of the elected chest 37. As sliown more clearly in Fig. 7 each set of contact members 76, 77 and 78 of each pipe 62 is adapted to be simultaneously operated with a set of contacts 9 and l0 of a pipe 38 as both sets of contacts will be simultaneously engaged with one of the lugs8 which is carried by each abstract 3. Therefore it is to be seen that when a piano key is operated the meclia nisms pertaining to a bass pipe and an organ pipe will be actuated. lt is of course to be understood that only a certain number of the piano keys are coperable with the bass pipes, in unich case other keys are only aeapted to operate one set of contacts 9 and lO of the organ pipes, as shown in Fig. 7.

ln order to produce prefect harmony in connection with the bass pipesfbeing played by the ordinary piano keys, it is preferable to sound only one bass pipe at one time for the sounding of any desired number of organ pipes. ln this connection, attention is called to Figs. 8 and 9 in which when a number of the piano keys 2 are operated, the

operated lugs 8 will carry the contacting members 76 against their respective contacting members 78, thereby breaking the circuit of the contact members 76 and 77. ln this connection, the contacting members 76 and 78 will energize only one of the magnets 72, thereby allowing the contents of the bellows 69 to vent through the port 74 in which the valve 67 of the chest 63 will have moved from the port 65, while the valve 68 will simultaneously close the port 66, thereby allowing air pressure to enter the passageway 6a and sound the bass pipe 62.

From the aforesaid description of the circuit shown in Fig. 9, it is to be seen that all of the contacts 76 and 78 that are operated to the right of the first or lowest set of contacts 76 and 78 will be deenergized on account of its lowest contact member 76 being moved out of contact from the member '7 7, thereby breaking the circuit to the right of said lowest set of contacts as the lowest bass note played will automatically cut out the playing or sounding of any higher bass notes.A Therefore there will only be one bass note sounded at the same time that any number of organ pipe notes are sounded.

`What I claim is:

l. The combination of a series of keys, a series of organ pipes and a series of bass pipes1 a pair of electric circuits connecting said keys, organ pipes and bass pipes, and means adapted to be actuated by any one of said keys, whereby when a number of said keys are operated together, only one of said bass pipes is sounded.
